Spatially multiplexing physical uplink control channel (pucch) and sounding reference signal (srs)

A method for wireless communication by a User Equipment (UE) comprising:

• deciding to spatially multiplex a Physical Uplink Shared Channel (PUSCH) and a Sounding Reference Signal (SRS) for simultaneous transmission via different sets of one or more antennas;
• determining that Uplink Control Information (UCI) is to be transmitted using resources assigned for the PUSCH, and that at least a portion of time and frequency resources for the PUSCH is to be used for transmission of the SRS;
• determining a resource mapping pattern for mapping the UCI to the PUSCH resources, wherein the resource mapping pattern avoids collision of the UCI with the SRS;
• mapping the UCI to the PUSCH resources based on the resource mapping pattern;
• and
• transmitting the spatially multiplexed PUSCH and the SRS after the mapping.

A method for wireless communication by a Base Station (BS), comprising:

• indicating to a User Equipment (UE) that a Physical Uplink Control Channel (PUCCH) and a Sounding Reference Signal (SRS) are to be transmitted simultaneously within a same component carrier via different sets of one or more antennas at the UE;
• determining time and frequency resources for the PUCCH and the SRS to avoid collision of at least a portion of the PUCCH with the SRS;
• signaling the determined time and frequency resources to the UE;
• and
• receiving the spatially multiplexed PUCCH and SRS using the determined time and frequency resources.

A method for wireless communication by a Base Station (BS), comprising:

• deciding that a Physical Uplink Shared Channel (PUSCH) and a Sounding Reference Signal (SRS) are to be spatially multiplexed for simultaneous transmission from a UE via different sets of one or more antennas at a UE;
• indicating the spatial multiplexing to the UE;
• detecting that Uplink Control Information (UCI) is to be received using resources assigned for the PUSCH, and that at least a portion of time and frequency resources for the PUSCH is to be used for receiving a Sounding Reference Signal (SRS);
• determining a resource mapping pattern for mapping the UCI to the PUSCH resources, wherein the resource mapping pattern avoids collision of the UCI with the SRS;
• and
• receiving the UCI based on the resource mapping pattern.
